Apparatus, system, and method for recovering a multivolume data set

A computer useable medium storing a computer readable program, wherein the computer readable program when executed on a computer causes the computer to:

• physically back up a plurality of source volumes to a plurality of backup volumes, the plurality of source volumes comprising a data set, wherein source volume metadata specifying a location for the data set on the plurality of source volumes is stored in a catalog and no backup volume metadata locates a backup copy of the data set on the plurality of backup volumes;
• retrieve the source volume metadata for the data set from the catalog;
• locate the backup copy of the data set on the plurality of backup volumes using the source volume metadata;
• and
• recover the data set as a recovered data set from the backup copy of the data set on the plurality of backup volumes.

A system to recover a multivolume data set, the system comprising:

• a plurality of source volumes configured to store an instance of a data set;
• a plurality of backup volumes configured to store a backup copy the data set;
• a catalog configured to store source volume metadata specifying a location for the data set stored on the plurality of source volumes;
• a storage controller configured to manage the plurality of source volumes, the plurality of backup volumes, and the catalog, and comprising a storage device storing executable code and a processor executing the executable code, the executable code comprising
• a backup module physically backing up the plurality of source volumes to the plurality of backup volumes, wherein no backup volume metadata locates the backup copy of the data set on the plurality of backup volumes;
• a retrieval module retrieving the source volume metadata for the data set from the catalog;
• a location module locating the backup copy of the data set on the plurality of backup volumes using the source volume metadata;
• a recovery module recovering the data set as a recovered data set from the backup copy of the data set on the plurality of backup volumes;
• and
• a verification module verifying that the recovered data set is successfully recovered.

A method for deploying computer infrastructure, comprising integrating computer-readable code into a computing system, wherein the code executed by the computing system performs the following:

• physically backing up a plurality of source volumes to a plurality of backup volumes, the plurality of source volumes comprising a data set, wherein source volume metadata specifying a location for the data set on the plurality of source volumes is stored in a catalog and no backup volume metadata locates a backup copy of the data set on the plurality of backup volumes;
• capturing a data set size for the data set instance during the physical backup;
• retrieving the source volume metadata for the data set from the catalog;
• locating the backup copy of the data set on the plurality of backup volumes using the source volume metadata;
• recovering the data set as a recovered data set from the backup copy of the data set on the plurality of backup volumes;
• and
• verifying that the recovered data set is successfully recovered.
